High resolution lenses offer improved image quality

08 August 2015

Stemmer Imaging is adding further options to its range of high resolution lenses for machine vision with 9, 10 and 12 megapixel lenses from Ricoh, Kowa and Tamron.

Ricoh´s FL-BC series is a family of compact lenses for 9 megapixel cameras with sensor size up to 1in-CCD and focal lengths from 25 up to 75mm. The apertures of the four models cover F1.8, F2.4 and F 2.8 and allow for minimum object distances between 100 and 250mm. With filter threads of M40.5 x 0.5, C-mount camera mounts and locking screws for aperture and focus, Ricoh´s FL-BC family is a compact and reliable solution for applications using 9 megapixel cameras.

Japanese lens manufacturer Kowa now offers new 10 megapixel high resolution lenses for machine vision that provide up to 200 lp/mm centre resolution and a low distortion to maximise the performance in high-end inspection systems.

Incorporating Kowa´s wide-band coating and floating mechanism system, the JC10M lens series greatly reduces chromatic aberration from close distance to infinity and maintains a high transmission from visible to NIR.

The series’ short minimum object distance and the compact design with aspherical lenses allow for easy installation in compact machine vision systems. JC10M covers five models with focal lengths from 5 to 25mm.

Tamron has announced the new M111 series of 12 MP lenses. These 1.1" format lenses feature an image-sided focal length of 50.0mm, an F1.8 aperture, a minimum pixel size of 3.1µm and a minimum object distance of 400mm.

The filter thread is M49 x 0.75. A C-mount with locking screws protects the lens from vibration faults. Further models of Tamron´s M111 series will be announced later in 2015.
